Brain Age Checkup Assessment App

About this project

BrainAgeCheckup is the free, no-login half of Thinkie's product line: a five-minute cognitive assessment, built on the same Kawashima research as the paid Thinkie sensor, that anyone can take in a browser with no hardware and no account. It exists to get someone from curious to convinced before they ever hear about the $299 device.

That meant building an actual small product, not another marketing page: three timed mini-games (mental-speed arithmetic, pattern memory, and a number/letter tapping test), each with its own instructions, live scoring, and a final brain-age result benchmarked against the player's age group.

Every step, from instructions through gameplay, grading, and results, runs in the same session with no account required, and anonymized scores feed the age-group comparisons future players see. An optional email unlocks a detailed category breakdown and training recommendations, which is the one moment the product asks for anything back.

Engineering-wise this is closer to a small game engine with a scoring pipeline than a typical Sandpiper site, and it's the top of Thinkie's funnel: play the free test, see your score, decide whether the sensor is worth it.
